I was generally talking about the difficult of making
precise tips for use with STMs or AFMs.  There is a
bit of difference between a tip that will grasp carbon
monoxide securely and precisely and a tip that will grasp
adamantane (a 10 carbon molecule (I think) with a diamond
like bonding structure).  If you only want to add one type
of molecule to a structure you never need to change tips.
If you do then you probably need a variety of tips to
get the job done.  View the tips as the wrenches and sockets
you need to take apart your car engine.

I think Alex is either in MI or TX, I can never keep track
of everyone.
